Abstract
Disclosed herein is an adaptive motion estimation and mode decision apparatus and method for an H.264 video codec. The apparatus includes a background image detection unit, an inter mode inspection unit, an intra mode inspection unit and a mode inspection skip unit. The background image detection unit inspects whether a fixed background or slowly and regularly moving block exists, and skips the step of dividing a first corresponding macroblock into smaller sized blocks and performing block mode inspection. The inter mode inspection unit inspects whether an irregularly or fast moving macroblock exists, and determines whether to divide a corresponding macroblock into smaller sized blocks and to perform block mode inspection on the smaller sized blocks. The intra mode inspection unit performs AZCB inspection on the macroblocks, and determines whether to divide a corresponding macroblock into smaller sized blocks block and to perform mode inspection on the smaller sized blocks. The mode inspection skip unit skips the block mode inspection for the smaller sized blocks.
